Gosh, of all the database sites I like your layout the best.   Content is frequently good (not always a given in the MSSQL Server world.

More than anything, I'd like more high quality content.   But since you asked about design, look toward making a higher volume of archives easy to find things in. 

As for content, I know you rely on your readers for that and I wish I had the time to do "What Microsoft Didn't Tell You about Installing Version 9 on X64..." (Short answer is that once you ARE running, 8 dual core Operterons with 64 Gig memory and iSCSI arrays are awesome powerwise: but you may end up reinstalling from the OS up about a dozen times before you learn all the ways you can screw it up)

Problem on content is: the good people are busy!
